FREEZIN'G CAN.

Application filed August 24, 1920. Serial No. 405,693.

To all whom t may concern.'

Be it known that l, ANsoN J. BENTLEY, a citizen of the United States, and a resident of the city of Niles, in the county of Trumbull and State of Ohio, have invented an Improvement in Freezing Cans, of which the following is a specification.

This invention aims to improve icefreezing cans wherein air on fluid is conducted to the interior of the 4cans near the.

base thereof, and more particularly the invention relates to the air or fluid-conducting` apparatus and to the method of attaching the same to the cans.

A selected embodiment of the invention is illustrated in the drawings, wherein- Figure 1 is a perspective view of an icefreezing can;

Figure 2 is a detail view r'of the fluidconducting apparatusin normal position;

Figure 3 is a sectional view of the apparatus taken on the line 3-3 of Fig. 2;

Figure 4 is a perspective view of a fixture;

Figure 5 is a sectional view of the 'fixture taken on the line 5 5 of Fig. 4;

Figure 6 is a view of the mandrel; and

Figure 7 is a view in section of a modified form of tube in position in the groove of the can.

In the particular embodiment of my invention selected for illustration herein, and shown in the drawings, referring first to Fig. 1, a freezing can 1 of desired shape and character such, for insta-nce, as generally employed in the manufacture of artificial ice is illustrated, the same having the base 2 and the sides 3, 4, 5 and 6. Preferably the sides 3 and 5 are wider than sides 4 and 6 so that the ice cake formed therein will be of the well known rectangular shape.

Tn the manufacture of the artificial ice cakes these freezing cans are usually filled with water and placed in a brine solution,

Y and it is customary to agitate the water during the freezing. To this end the agitation or-stirring of the water is preferably accomplished by introducing air or fluid into the water near the bottom of the can. The air may be conducted to the lower end of the can by any well known means. as for example a. usual tube 7 assembled in a channel 8 which is impressed in one of the sides of the freez ing can.- Tubes having desired shapes of l Y cross sections may be employed and theY channels `will be suitably formed, as shown. to receive the saline.- The air is preferably introduced` into the interior of the can at a point just above the base and for this the side .of the can, preferably as in the channel portion, is provided with an aperture 9. The tube 7 as assembled in the channel preferably has its lower end located adjacent this opening 9, and a fixture 10, as illustrated in Figs. 4 and 5, is assembled in the lower end of the channel and over the end of the tube to direct the air from the end of the tube to and through the aperture or opening 9. The fixture is conveniently made as a fit- Ytube to the interior of the can. This fixture or clip is desirable as it is quickly and cheaply manufactured and may be quickly assembled and held in position.

A convenient method of assembling the fluid-conducting apparatus in proper position consists in assembling the mandrel 1.4, illustrated in Fig. 6, in the tube 7 by inserting the end 15 of the mandrelin the tube. The tube and mandrelare then placed in the channel 8. as illustrated in Fig. 3, with the free end of the mandrel extending to the interior of the can and preferably contacting with the metal of the can at the top of the opening 9. The fitting 10 is then placed in the channel and over the end of the tube. The lowest end of the convex part of the fitting contacts with a shoulder 16 formed in the end of the channel where it graduates to the original outline of the can. The shoulder 13 in the fixture is properly positioned opposite the opening 9 when the end of the fixture sets on the shoulder 16. A pocket is formed between the channel and the concave part 12 of thevfixture forreceiving the end of the tube. and flanges 17 and 18 conform ro the shape of the channel to assist in holdn ing the fixture in position. Next the solder or other fastening means is applied to hold the tube and fixture to the freezing can and to each other. The mandrel during this step operates to prevent the solder from filling the opening in the tube or the opening 9.

After the soldering is completed the mandrel is removed, and an unobstructed passageway for air or fiuid from the top of the freeiing can to the interior thereof near its base is obtained.

Referring to Fig. 7, the fixture is shown as applicable to thelower end of a tube which is bent to partially enter the opening 9.- ln this arrangement the holding means such as solder is applied to the fixture and to the channel` and to parts of the tube extending above the fixture thus firinly holding the tube in position. In assembling the tube with the bent end the use of the inandrel let is obviated as the tube is laid in jthe channel S Vwith part of its lower end held in the opening 9 thereby positioning itself and filling the opening 9 so that the solider will not enter and fill the air passage.

rlhe invention may be variously embodied and the particular form of apparatus herein shown niay be modified within the scope of the subjoined claims.

I claim:

l. A freezing can for use in the inanufacture of ice having one wall inwardly grooved from the top of the can substantially to the bottom thereof, the inner wall of said groove being perforated near. its lower end, on air tube located. and fastened securely in said groove and extending from the upper edge of the can to a point adjacent the perforation in the groove, and aI fixture forming a fluid tight connection be tween the tube and th'e interior of the can fitting said groove and provided with a longitudinal recess in its inner side which cooperates Ywith the groove bottom to receive the end of the tubeY adjacent the perforation.

V2. Afreezing can for use in the manufacture of ice having a U shaped channel formed in one of its sides and extending substantially the full length thereof and having an opening in said channel leading to the interior of said can, an unbent air tube located in said channel, and a grooved fixture having a shoulder therein and being mounted in saifdchannel with said shoulder opposite said opening, said fixture receiving the end of said tube and effecting a connection between the end of the tube and the opening in the groove. Y Y

3. A freezing can for use in the ifnanufacture yof ice lia-ving a U-s'haped channel formed in one of itssides and Vextending substantially the full lengtli thereof and having` an opening in said channel leading to the interior of said can, an air tube extending along said 4channel from the ltop of the can substantially to said opening and a stamped fixture forming an air tight connection betweenl the air tube and the opening, said fixture being generally of U-shape in Cross section, fitting in said channel and hav-ing a portion of the fixture reversely grooved forming with the channel bottom a recess to receive and lit the air tube.

4. A freezing can for use in the manufacture of ice having a U-shaped channel formed in one of its sides and extending substantially the full length thereof and having an opening in said channel leading to the; interior of said can, an air tube extending along said channel from the topof the can substantially to the opening and a stamped Vfixture substantially of v Ushape in cross section fitting in said channel at the opening, having a portion above the opening reversely grooved to forni withthe channel bottoni a cylindrical recess to receive the air tube, said fixture forming an air tight connection between said air tube andthe interior of the can. y Y Y In testimony whereof, I have signed my name to this specification this 21st day of August, 1920.
